  • Patent number: 12189043
    Abstract: In an aspect, a user equipment (UE) receives a spoofing alert message from either a server or an internet-of-things (IOT) device that indicates whether a spoofed Global Navigation Satellite System (GNSS) condition is present. Based on determining that the spoofing alert message indicates that a spoofed GNSS condition is present, the UE determines, based on the spoofing alert message, a location of a spoofer broadcasting a spoofed GNSS signal, determines, based on the location of the spoofer and a current location of the UE, that the UE is within a receiving area of the spoofed GNSS signal, and determines a position of the UE without using the spoofed GNSS signal.

The method includes sending at least one measurement command from the server to the measurement device to cause the measurement device to obtain the first positioning signal measurements in accordance with the measurement times and/or obtain second positioning signal measurements of second positioning signals sent from the subset of positioning signal sources. The method includes: receiving, at the server from the measurement device, measurement data corresponding to the first positioning signal measurements and/or the second positioning signal measurements; and determining, at the server, the location of the measurement device based on the measurement data.

  • Publication number: 20240337755
    Abstract: A Precise Positioning Engine (PPE) may use correction information to perform highly accurate Global Navigation Satellite Systems (GNSS) positioning. Transitioning between, or “swapping,” of a first correction information source (e.g., Real-Time Kinematic (RTK) base station) with a second correction information source may be handled using correction information from the first correction information source to update a first state of the PPE. The updated PPE can then be modified by initializing at least ambiguity values of the PPE state. Correction information from the second base can be used to further update the PPE to a second state without a time update at the PPE. By employing this process, embodiments can reduce sudden changes in position estimation due to correction information source swapping, which can often result in resetting of the PPE and a reduced user experience quality.

  • Publication number: 20240319385
    Abstract: Techniques for precise positioning using differential carrier phase (DCP)-based measurement updates are disclosed. The techniques can include obtaining a pseudorange observation for a positioning epoch and a carrier phase observation for the positioning epoch based on measurements of global navigation satellite system (GNSS) signals transmitted by one or more space vehicles (SVs) of a GNSS constellation, generating a differential carrier phase observation for the positioning epoch based on the carrier phase observation for the positioning epoch and a determination that real-time kinematic (RTK) correction data associated with the GNSS constellation is unavailable, and generating a position, velocity, and time (PVT) observation of the mobile device for the positioning epoch based on the differential carrier phase observation for the positioning epoch.

  • Publication number: 20240241263
    Abstract: Position, Velocity, and Time (PVT) information of a LEO satellite can be determined by leveraging a known position of a mobile device comprising a terrestrial satellite receiver of the LEO satellite and using range information (range and/or range rate) of the LEO satellite taken at the mobile device. According to some embodiments, this PVT information can be shared by the mobile device with the server and/or other mobile devices, and information from multiple mobile devices can be crowdsourced to determine robust PVT information for a LEO satellite. Once the PVT information is determined, it can be used to subsequently for positioning of the mobile device and/or other mobile devices.

  • Publication number: 20240142640
    Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a vehicle to determine location relative to a roadside unit (RSU) or other nearby point of reference. Vehicles within a pre-designated range or within broadcast distance or otherwise geographically proximate to a roadside unit, through the use of broadcast or other messages sent by the vehicles and/or the RSU may share carrier GNSS phase measurement data, wherein the shared GNSS carrier phase measurement data may be utilized to control and coordinate vehicle movements, velocity and/or position by the RSU and/or to determine location of each vehicle relative to the RSU and/or to other vehicles or determine the absolute location of each vehicle. An RSU may coordinate vehicle access to an intersection, manage vehicle speeds and coordinate or control vehicle actions such as slowing, stopping, and changing lanes or sending a vehicle to a particular location.

  • Publication number: 20230417855
    Abstract: Aspects presented herein may improve the performance and accuracy of RF-based positioning. Aspects presented herein may enable a device to use RF Doppler measurements to detect and mitigate multipath effects in RF-based positioning. The RF-based positioning may include satellite navigation, terrestrial positioning system, and/or indoor positioning. In one aspect, a UE receives, via a receiver, signals from one or more entities. The UE determines whether each received signal is a multipath signal based on a Doppler shift measurement. The UE de-weights or excludes one or more signals of the received signals in estimating a position of the UE based on whether the respective received signal is determined to be a multipath signal.

  • Publication number: 20230204796
    Abstract: Global Navigation Satellite System (GNSS) receivers can provide more accurate positioning when augmented using Real-Time Kinematic (RTK) or Differential GNSS (DGNSS) corrections. Techniques described herein leverage multi-constellation, multi-frequency (MCMF) measurements taken at a base station at first and second times to generate correction information that can be used to detect and correct a bias (or offset) in the location of the base station. This bias may be detected by a rover station, or by the base station itself.

  • Patent number: 11668840
    Abstract: A Real-Time Kinematic (RTK) solution is provided to mobile devices having multi-constellation, multi-frequency (MCMF) functionality, in which a single base station may have a baseline much farther than traditional base station. To enable this, embodiments account for differences in atmospheric effects between the rover station and base station when determining a GNSS position fix for a mobile device (rover station), allowing for a separate tropospheric delay error for a base station to be determined. Embodiments may use additional satellite measurements for which no RTK correction is available, and may further use orbital clock correction for these additional satellite measurements.
